The Labrador breed has a lifespan of 10 to 12 years. Some of the general health conditions that afflict Labradors are patellar luxation, canine hip dysplasia (CHD), and osteochondritis dissecans (OCD), which is canine elbow and shoulder dysplasia. This breed also occasionally suffers from distichiasis, exercise-induced collapse, diabetes, muscular dystrophy, tricuspid valve dysplasia, and entropion. Minor health concerns include retinal dysplasia, central progressive retinal atrophy (CPRA), hypothyroidism, hot spots, and cataract. Knee, hip, eye, and elbow tests should be included in the usual medical check-ups.
Labrador retrievers are easily recognized by their broad head, drop ears and large, expressive eyes. Two trademarks of the Lab are the thick but fairly short double coat, which is very water repellent, and the well known "otter tail." The tail is thick and sturdy and comes off the topline almost straight. The feet are described as "webbed," with longer skin between the toes to aid in swimming. Color can range from black through chocolate to a red/yellow or even almost white.
